Application filed August 19,1925. Serial No. 51,139.

This invention relatesto a gas burner and more especially it relates tosuch a burner intended to heat a steam drum for generating steam to bemixed with oil for furnace heating, although as will be seen, it isadmirably adapted for steam generation for other purposes.

The primary object of the invention is to make the burner mechanismautomatic in its action, that is to say, it embodies a construcv tion inwhich the gas is cut off, and consequently the flame is extinguished,and the gas re-lighted according to the exigencies and requirements ofuse.

A further object is to' so construct the mechanism that it will bedurable and simple in construction and not likely to get out of orderand be reliable and dependable in operation.

A still further object of the invention is to so construct themechanismthat the consumption of gas will be reduced to a minimum whichobviously results from the fact that the gas is entirely out off fromthe burner when the burner is in its lowermost position,

or the position inwhich its flame is not needed for the generation ofsteam.

In the drawings- Fig. 1 is a View somewhat diagrammatic or schematic incharacter showing the burner in raised or operative position below thesteam drum, there being shown in dotted lines, the lowermost position orthat in which the gas flame isextinguished. v

Fig. 2 is a plan view of the gas cock partially in section.

Fig. 3 is a cross section taken about online aa of Fig. 2.

Fig. 4c is a central section of the nozzle at which is maintained thefurnace heating flame. Referring to the drawings, the numeral 1designates the steam drum that may beof any approved" construction. butpreferably of flattened'ovoid shape, as shown. This contains a steamcoil 2 having small perforations 3 therein. To the lower portion of thedrum is connected a vertical steam pipe 4 which hasits lower end letinto the nozzle 5, which nozzle will later be described in detail.

Connected to the lower endof the nozzle is an oil pipe. 7 leading to anysuitable source of oil supply, and as will later appear, the action ofthe steam from thesteam drum issuing through the nozzle, which speciallycon:

structed, will act as an, injector to draw the oil into the nozzle to.be therein mixed with the steam and air, which mixture is ignited at thenozzle to maintain an intense heat within the furnace, for instance, themixture constituting a fuel to. take the place of'coal or furnaces. IThe more important part of my invention which I now stress has to dowith the burner 'mechanismi The numeral 8 designates the gas cock, andby reference to Fig.2 this will be seen to be constituted by a base 9for attachment to any suitable support and a short upright or standard10 which terminates in a laterally extending conical key 11 surroundedby a snugly fitting rotatable body or sleeve 12. This sleeve is providedon one side with an apertured internally threaded boss 13, the aperturebeing Virtually a continuat on of the hole 14 in the sleeve, which holeat times is adapted to register with a port 15 i in the wall of the key,which port communicates with a chamber 16 in said key.

Threaded into the key and opening in said chamber is the' nipple 17 uponwhich is threaded the T connection 18, to which in turn is connected inthe usual way the gas inlet pipe 19 communicating with the house main,or other source of gas supply. Threadedinto the T and communicating withthe gas source is a pilot burner 20 whose open outer end extendsintoclose proximity to the nozzle 5, as clearly shown in the main figure, soas will presently appear, it will always be in poother combustiblematerial commonly used in sition to re-ignite' the Vapor at'the nozzlewhen-necessary or desirable in" the opera tion of the mechanism. Thispilot burner, as

just, intimated, is maintained constantly throughout the entire time, inwhich it is desired tobring about automatic operations of the mechanism.1 I

Threaded into the threadedopening inthe boss 13 is the burner tube21,Which is bent atits outer end to form a circular burner 22 having inthe top thereof aseries of properly spaced and sized holes 23 inposition to direct the flame against the bottom of the steam;drum, thecircular formation of the burner.- permitting it to surround the steampipe 4 leading from the drum to the nozzle.

Preferabl I arrange the'holes in the burner at an an e so that when itis in raised post tion under the drum, the flame will be directe'd intrue vertical direction because when the burner is in raised position,it is the only time that the gas cock is open and that the flame isextant.

On the side of the sleeve opposite the burner tube is an arm 24-bifurcated as indicated at 25 for the reception of the upper endofashort link 26 which is pivoted in the bifurcation as shown. The lowerend of the link is pivoted at 27 in a similar bifurcation in the upperend of a piston rod 28 which 8X- tends through a properly packedstufling box 29 formed in a cap 80 which closes the upper end of a steamcylinder 31, the rod being provided with a piston 32. The lower end ofthe c linder is closed b a can 33' into the bottom of whichis threaded ashort pipe 34.- having a branch 35 connected w1th a steam pipe 36, which111 connection with the nozzle will be presently described. The

cap 33 at the bottom of the cylinder is provided with a flange 38 towhich are attached the lower ends of two spiral springs 39 whose upperends are attached to a cross bar 40 carried by the piston rod, thesprings exerting their force to bring the piston to its lowermostposition in the cylii'ider, thereby raising the burner and opening thegas cook.

The water supply in the steam drum may be regulated by a suitablethermostat opcrating through a rod a upon a suitable valve Z). Thisthermostat operates to supply water to the coil when necessary, andsince the burner is operated by steam pressure, as will later appear,through the cylinder and its connections with the burner, there will beno steamwhe'n there is no water, but the drum will be in a highly heatedcondition due to the fact that the burner will be in raised position andthe cock open and in readiness to generate steam immediately thethermoactuates the valve governing the water supply to the coil.

The key of the burner, it will be observed,

is somewhat like the lrey in an ordinary gas fixture except in thepresent instance, ltlS differently chambered and there is provided asindicated at 4:1 the usual nut for drawing the key into the sleeve tobring about the necessary tight fit between the key and body. Referringparticularly to Fig. 4;, it will be noted that the nozzle 5 is of shellformation, and as shown preferably conical. It

has a flame orifice 6 communicating with a chamber 'A. In thls chamber1S a core B somewhat smaller than the chamber and shaped like thechamber, so that a space 6 will be left between the walls of. the shelland the core. The core is chambered as indicated at D, communicatingwith this chamher is a pipe E, which with the chamber D virtually formsa continuation of the steam pipe l. Extending upwardly from the chamberD to the space around the core are a series of perforations F, thepurposes I of which will be presently described.

mission of air into the nozzle in the operationiof the device. Let intothe bottom of the nozzle is an oil supply pipe 7 leading toanysuitable-source of oil supply, and it will be noted that the pipe Eextends centrally through the pipe 7 andpasses therefrom. The pipe Eextends some distance beyond the oil pipe and is fitted with a: T towhich is connected as shown, the pipe 36 through which steam passesto-the cylinder through the branch 35 as shown, the branch pipe beinglocated just above the drain cook 36. I preferably extend the pipe/Ebeyond its connection with the pipe 36 and provide the extension whichis designated by H with a gauge 1 and the lower end of the pipe H ispreferably provided with a trap JJ In operation water is supplied to thecoil 2 and with the parts as shown in the position in full lines in themain figure,=the ports in" the sleeve and key will be'in registry andthe gas turned on. Atth'e start the burner and pilot are lighted with amatch, the dome heated and water turned on. If the dome is well heated,formation of'st'eam'is almost instana taneous, and the steam passesthrough the steam pipe 4, into the nozzle 5 in which it is mixed withthe oil and air and sprayed into the zone that it is desired to heat.The steam passing into'the core B is divided, part pass ing into thepipe E and part deflected through the perforations Ftoward the top ofthe nozzle. The portion of the steam whose direction is reversed andcaused to pass through said perforations acts as an injector to draw theoil or oil vapor into the nozzle for ignition at the top of the nozzle.At the same time by the same injector force airis drawn into the nozzle"through theperforations G so that there isa mixture in the nozzle ofsteam, oil, or oil vapor and air, which when ignited maintains, as isobvious, an in Ill) in the cylinder the springs 39 will draw thecylinder to its lowermost position, raising the burner to position togeneratesteam in the drum, the burner being re-lighted bythe'dying'flame above the nozzle.
